What to Do:
A should be able to identify and resolve update ( as FT_Prog) to check if the settings (e.g., USB interface type, baud rate) are correct.
How to Check:
Open FT_Prog, read the device settings, and confirm that they match the intended configuration for your application. Make adjustments if necessary.
Step 5: Verify Power SupplyWhat to Do:
Ensure that your FT2232HQ is receiving sufficient and stable power. If you’re using external power, try using a different power source or USB port.
How to Check:
Check the voltage levels (typically 3.3V or 5V depending on your configuration) using a multimeter. If the power supply is unstable, the FT2232HQ might not function properly after the firmware update.
Step 6: Test with a Known Working SetupWhat to Do:
If possible, test the FT2232HQ with a known working setup (i.e., a system where it worked previously). This can help isolate whether the problem is related to the firmware update or your current system setup.
How to Check:
Plug the FT2232HQ into a different computer or USB port and observe if the issue persists. If the chip works on another system, the issue might be specific to your current machine or setup.
Conclusion
If your FT2232HQ isn't working after a firmware update, the issue can usually be traced back to one of the causes mentioned above. By following this guide, you can systematically troubleshoot the problem and restore functionality to the chip. Start with verifying the firmware version, update the drivers, check the power supply, and consider reflashing the firmware if needed. Most importantly, taking the time to follow each step will help pinpoint the root cause and resolve the issue in a clear, organized manner.
If the issue still persists, consider reaching out to FTDI's support team for further assistance.
